After resizing, batik rendering get's strange behavior. Sometimes, on smaller
window, parts get rendered doubled on the downside or cheesy background stays

works. Making the window big again, somehow magically repairs the rendering.
If I had to guess something goes bad in the SWT<->Swing connection
on resize. My best guess would be the problem is related to our update
handling. In particular you might look at JSVGComponent in particular
the 'updateCompleted' method (~line 1971). I could imagine that the
'repaint' and/or paintImmediately could have problems, especially given
the use of invokeAndWait.
Ok, I try to search for it.
You might see if doing a simple repaint of everything avoids the
issues (this would be less efficient but much more efficient than
setting the whole document).
Unfortunately repaint doesn't help. Actually the behavior is little
deterministic. In some composite constallations the problem of wrong
rendering of some parts somewhere gets solved, but still batik dynamic
rendering gets stucked.
So if anyone has an idea just how to revive it, would be great and solve
my main problem! What worked out for example was to set deactivate the
layout manager, set the JSVGCanvas size to 0 and back, reactivate and to
call repaint or to change and set the document again. ;)

Michael
